摘要: MoS2作为一种润滑剂已被广泛应用和研究，但是其在摩擦过程中界面微观结构的变化和摩擦机理相关性很少报道。本文采用机械擦涂方式在不锈钢表面制备了MoS2固体润滑薄膜并考察了与GCr15球、Al2O3球和Si3N4球的摩擦磨损性能。利用场发射扫描电镜(FE-SEM)和拉曼光谱仪(LABRAM HR 800)分别对薄膜结构及其在摩擦过程中结构变化进行表征；利用往复式摩擦磨损试验机(MFT-R4000)、三维表面轮廓仪(MicroXAM-3D)分别研究了薄膜摩擦磨损性能和磨损情况。结果表明：在三种不同对偶条件下所制备的MoS2薄膜均表现出良好的润滑性能，降低接触表面的摩擦系数约80%左右(涂覆前µ~0.5，涂覆后µ~0.1)，同时有效减少不锈钢表面的磨损(5 N时降低18%左右，10 N时降低35%左右)。拉曼光谱证实MoS2薄膜在摩擦力的作用下层状剥离形成磨屑和层间低剪切力是降低摩擦磨损的主要原因。
Abstract: MoS2 has been widely used and thoroughly studied as a solid lubricant for a long time, but the re-search on relationship of the structure evolution and frictional mechanism are seldomly reported. In this paper, MoS2 solid lubricating films were prepared on the surface of stainless steel by me-chanical rubbing. Then we used GCr15, Al2O3 and Si3N4 ball as couple pairs to investigate the friction and wear properties on a reciprocation tribo-tester (FMT-R4000), the loads for tests were 5 N and 10 N. Field emission scanning electron microscopy (FE-SEM) and Raman spectroscopy revealed the structure evolution of MoS2 during the course of friction. Three-dimensional surface profiler (MicroXAM-3D) was used to characterize the surface topography of wear tracks. The results indi-cated that the friction coefficient of stainless steel was reduced by 80% (before coating ~0.5 and af-ter coating ~0.1), and the wear volume was reduced by 18%, 35% when the load was 5 N and 10 N, respectively. These excellent properties suggest that mechanical rubbing is an effective method for solid lubricating film preparation. In addition, Raman spectroscopy also confirmed that the layered peeling and interlayer low shear is the main reason to reduce friction and wear.
